The Bank is exposed to market risks that may cause losses in both on and off-balance sheet assets and liabilities as a result of adverse changes in market prices (interest rates and exchange rates). As to market risk management for the trading book, exchange rate risk mainly arises from foreign exchange transactions in which The Bank is engaged on its own account or on behalf of customers. The

The operational efficiency and risk prevention ability were continuously enhanced. The approach that The Bank calculate equivalent operational risk-weighted asset is Basic Indicator Approach (BIA Method), and the specific method is to utilize the average of three years adjusted gross income multiplied by 15%. 2.4 Disclosure on interest rate risk in banking book 2.4.1 General qualitative information and nature description Interest rate risk in the banking book arises mainly from mismatches in the maturities, re-pricing periods or benchmark interest rates of assets and liabilities. For general businesses, Thai baht deposits are mainly used for loans, bonds, investment and to meet the liquidity requirements. Most of the loans is dominated in USD (out-out business), funded by the Head Office with term mismatched. The Bank adjusted the interest rate several times in 2017 considering the situation of market. The major interest rate risk in banking book is between the USD capital fund from Head office that The Bank shall pay interest rate at 1 month LIBOR and while the utilization of the capital fund in majority invests in the fixed-rate long-term Thai baht bonds, the reasons of no hedging are The Bank s long-term business plan and the head office of the relevant policies. 2.4.2 Key assumptions used for risk assessment and Frequency of interest rate risk in banking book measurement The Bank manages the interest rate risk of the banking book primarily through interest rate repricing gap analysis. The data generated by gap analysis is used to perform sensitivity analysis, assist decision making regarding the re-pricing of the interest-earning assets and interest-bearing liabilities. The analysis report is used for illustrative purpose, and is based on The Bank s gap position and key assumptions are using the percentage changes in interest rates of 100 bps and not considering any change in customer behavior.
